Vanguard Lays Groundwork for Potential Switch
to New Indexes
By John Spence,
Associate Editor
Retail index fund giant Vanguard today filed a preliminary proxy
statement with the SEC seeking shareholder approval on several investment
policy changes for many of its index funds.
In a move that may presage a shift to new benchmarks for many of
its index funds, Vanguard is seeking approval of a policy change
that would authorize fund trustees to change target benchmarks if
they deemed shareholders would benefit. The trustees of 19 Vanguard
index funds are already empowered to change target indexes at any
time.
Winds of change blowing?
Vanguard index fund manager Gus Sauter raised eyebrows in the industry
when he wrote an article for last quarter's edition of The Journal
of Indexes that was critical of current index methodologies.
In the article, Sauter even outlined techniques index providers
could use to reflect market segments in a way that would be friendlier
to passive managers like himself. Specifically, Sauter called for
index objectivity and transparency, adjustment for cross-holdings,
and new methods for determining growth and value.
"That article was a compilation of my thoughts on index best
practices after 16 years of experience," said Sauter in an
interview.
In a statement released today, Sauter hinted that Vanguard's ideas
on index construction could move from theory to practice.
"We regularly evaluate the target benchmarks of our index
funds to ensure that they are constructed appropriately to reflect
the performance of a given market. In addition, we examine other
indexes in the marketplace for potential use as benchmarks for our
funds or the development of new funds," said Sauter. "Over
time, we've developed our own views with respect to best practices
in index construction and rebalancing methodology. Index providers
have been exploring many of these same ideas and we are beginning
to see opportunities open up that we believe may be worth pursuing."
In the statement, Vanguard announced that it has secured the right
to use new U.S. stock indexes under development by Morgan Stanley
Capital International (MSCI). Vanguard said it likes the methodology
the new MSCI indexes are expected to employ. However, Sauter noted
that Vanguard is not obligated to adopt the new MSCI indexes.
"Nothing is set in stone yet," he said.
Today's proposal applies to the following Vanguard index funds:
Total Stock Market (Wilshire 5000), Extended Market (Wilshire 4500),
SmallCap (Russell 2000), Growth (S&P/Barra 500 Growth), Value
(S&P/Barra 500 Value), Mid-Cap (S&P 400), SmallCap Growth
(S&P/Barra 600 Growth), and SmallCap Value (S&P/Barra 600
Value).
Vanguard said it has no plans to change the benchmark for its S&P
500 index fund, which is the largest mutual fund in the U.S. with
about $63.9 billion in assets, according to Morningstar.
Morningstar senior fund analyst Scott Cooley said the performance
of Vanguard's large-cap style index funds, as well as the turnover
in its small-cap funds, may have triggered today's announcement.
"The returns of Vanguard's large-cap style index funds were
similar last year, although by all accounts 2001 was a stellar year
for value," said Cooley.

Cooley notes that the S&P/Barra indexes tracked by these funds
only use one variable to separate growth and value - price-to book
ratio (p/b) - while other index providers use more metrics. Vanguard
has also been concerned about high turnover in its small-cap index
funds, said Cooley.
Moving to non-diversified status
Additionally, Vanguard is seeking shareholder approval to reclassify
many of its index funds as "non-diversified" under securities
laws.
A "diversified" index fund runs into a problem when its
benchmark becomes dominated by a few big stocks. For example, in
May 2001 shareholders in Vanguard's Growth index fund approved a
similar proposal when four stocks - Microsoft GE, Cisco, and Intel
- became so large the fund violated diversification rules.
Diversification rules have also been a problem for Barclays Global
Investors' iShares Sweden ETF, which was forced to rebalance when
a few names in the index grew too large.
Vanguard's Sauter said non-diversified status is appropriate for
Vanguard's index funds because they should reflect a market index
regardless of how big individual stocks grow. However, Morningstar's
Cooley noted that the last few years have shown the benefits of
the diversification rule because investors have not been overly
exposed to "bubble" companies on the way down.
